Lautsprecher, insbesondere Radio-Lautsprecher.
EMI1.1
<Desc/Clms Page number 2>
In Fig. 6 sind die beiden Trichter so voneinander verdreht, dass ihre Schallwellen auseinandergeben.
In Fig. 7 sind die beiden Trichter zueinander und nach oben verschwenkt, wozu bei 7, 8 Gelenkzapfen dienen.
An Stelle der Schalltrichter können äquivalente Mittel, wie Teller oder. andere Hallvorrichtungen, wie sie in der Lautsprechertechnik Verwendung finden, benutzt werden.
Die Praxis hat in vielen Räumen ergeben, dass die günstigste Entfernung der Dreh-oder Gelenkzapfen 7, 8 ungefähr gleich der mittleren Entfernung der beiden Ohren am erwachsenen Menschen, d. i. ungefähr 24 cm ist. Diese Entfernung kommt insbesondere bei der in Fig. 3 gezeigten Lage der Trichter zur Geltung.
Die Vorrichtung kann auch so eingerichtet sein, dass die Trichter od. dgl. im wesentlichen eine parallele unabänderliche Lage zueinander einnehmen und nur zur Erzielung des erwähnten Abstandes 15 auf beliebigen Führungen gegeneinander einstellbar sind.
Bei diesem System ist es auch möglich, Verlängerungsstücke an den Trichtern zu benutzen, wodurch unter. Umständen die Plastik des Schalles gewinnt.

EMI2.1
vorriehtungen, dadurch gekennzeichnet, dass die beiden Trichter od. dgl. so zueinander einstellbar sind, dass bei verschiedenen oder im wesentlichen parallelen Lagen zueinander sich die beiden Schallerzeuger in der Hauptrichtung des gemeinsamen Schalles in einem Abstand voneinander befinden, um eine plastische Wiedergabe der Laute zu erzielen.

In FIG. 6, the two funnels are twisted from one another in such a way that their sound waves diverge.
In Fig. 7 the two funnels are pivoted to each other and upwards, for which purpose at 7, 8 pivot pins are used.
Instead of the bell, equivalent means such as plates or. other reverberation devices such as those used in loudspeaker technology are used.
Practice has shown in many rooms that the most favorable distance between the pivot pins 7, 8 is approximately equal to the mean distance between the two ears on an adult, i.e. i. is approximately 24 cm. This distance is particularly effective in the position of the funnels shown in FIG. 3.
The device can also be set up in such a way that the funnels or the like essentially assume a parallel, unchangeable position to one another and can only be adjusted to one another on any guides to achieve the mentioned distance 15.
With this system it is also possible to use extension pieces on the funnels, whereby under. Circumstances the plastic of the sound wins.
PATENT CLAIMS:
EMI2.1
Vorriehtungen, characterized in that the two funnels or the like are adjustable to each other so that in different or substantially parallel positions to each other, the two sound generators are in the main direction of the common sound at a distance from each other in order to a plastic reproduction of the sounds achieve.
